An issue has been discovered in GitLab CE/EE affecting all versions from 17.2 before 17.11.5, 18.0 before 18.0.3, and 18.1 before 18.1.1 that could have allowed unauthenticated attackers to upload arbitrary files to public projects by sending crafted API requests, potentially leading to resource abuse and unauthorized content storage.
Solution:
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
